Description

La présente invention concerne une machine destinée à la destruc­tion de toute végétation croissant au-dessus du sol.
La présente invention concerne plus particulièrement une machine pour la destruction des fanes d'asperges.The present invention relates to a machine intended for the destruction of any vegetation growing above the ground.
The present invention relates more particularly to a machine for destroying asparagus tops.

Il est connu pour la destruction de la végétation, d'utiliser des broyeurs qui divisent la matière en particules.
Il est également connu de détruire la végétation par brulage.It is known for the destruction of vegetation, to use grinders which divide the matter into particles.
It is also known to destroy vegetation by burning.

Dans le premier cas, les particules de végétation tombent au sol et il peut y avoir transmission des parasites ou maladies dont étaient porteurs les végétaux broyés.In the first case, the vegetation particles fall to the ground and there can be transmission of parasites or diseases which were carried by the crushed plants.

Dans le deuxième cas, il est possible d'éviter les inconvénients causés par le dépot sur le sol des végétaux.
Cependant, le brulage peut etre néfaste pour les pousses, raci­nes ou autres contenues dans le sol.In the second case, it is possible to avoid the inconveniences caused by the deposit on the soil of plants.
However, burning can be harmful to the shoots, roots or others contained in the soil.

Le problème se pose particulièrement, mais non spécifiquement dans la culture de l'asperge.
Les fanes d'asperges doivent etre détruites pour permettre l'obtention des pousses ou asperges.The problem arises particularly, but not specifically in the cultivation of asparagus.
The asparagus tops must be destroyed to allow the shoots or asparagus to be obtained.

Ces fanes sont les vecteurs de transport de maladies qui affaib­lissent la souche et réduisent ses capacités de production dans le temps.
Le broyage communément utilisé n'apporte pas de solution à ce problème.
Le brulage des fanes sur le site de culture n'est pas davantage adapté car cette opération risque d'endommager la souche ou grif­ fe.These haulms are the carriers of diseases that weaken the strain and reduce its production capacity over time.
The commonly used grinding does not provide a solution to this problem.
Burning the haulms on the culture site is no more suitable because this operation may damage the stump or grif fe.

L'invention vise à obvier aux inconvénients sus-mentionnés en réalisant une machine destinée à la destruction sur le site de culture de la végétation parasite telles que les fanes d'asper­ges.
A cet effet, la machine selon l'invention qui est du type trac­tée, portée ou automotrice se caractérise en ce qu'elle est cons­tituée par la combinaison d'un organe de coupe définissant une zone de coupe des fanes, d'un organe de destruction de fane par brulage définissant une zone de destruction et d'un organe de translation des fanes coupées d'une zone vers l'autre, le dit organe ayant également une fonction d'obturation entre les dites zones.The invention aims to overcome the above-mentioned drawbacks by making a machine intended for the destruction on the site of cultivation of parasitic vegetation such as asparagus tops.
To this end, the machine according to the invention which is of the towed, carried or self-propelled type is characterized in that it is constituted by the combination of a cutting member defining a haulm cutting area, of a destruction of haulm by burning defining a destruction zone and a member for translating haulms cut from one area to another, said member also having a shutter function between said areas.

D'autres avantages et caractéristiques de l'invention apparait­ront à la lecture de la description ci-après de formes de réali­sation de l'invention données à titre d'exemple non limitatif et illustrée par les dessins joints, dans lesquels :

  • - la figure 1 est une vue schématique en coupe d'une forme de réalisation,
  • - la figure 2 est une vue de face de la machine selon la figure 1
  • - les figures 3 et 4 sont des vues de la machine suivant une aut­re forme de réalisation de l'invention.
Other advantages and characteristics of the invention will appear on reading the following description of embodiments of the invention given by way of non-limiting example and illustrated by the accompanying drawings, in which:
  • FIG. 1 is a schematic sectional view of an embodiment,
  • - Figure 2 is a front view of the machine according to Figure 1
  • - Figures 3 and 4 are views of the machine according to another embodiment of the invention.

Telle que représentée en figure 1, la machine selon l'invention comprend un organe de coupe 1 au niveau duquel est définie la zone de coupe 1A, un organe de destruction 2 définissant une zone de destruction 2A et un organe 3 de translation et transport des fanes coupées de la zone de coupe vers la zone de destruction.As shown in Figure 1, the machine according to the invention comprises a cutting member 1 at which the cutting area 1A is defined, a destruction member 2 defining a destruction area 2A and a member 3 for translating and transporting haulms cut from the cutting area to the destruction area.

L'ensemble des organes et éléments d'actionnement de ceux-ci est porté par un chassis non représenté à la figure 1.
Ce chassis peut etre attelé avec moyen de roulement ou de glis­sement, porté ou automoteur.All the organs and actuating elements thereof are carried by a chassis not shown in FIG. 1.
This chassis can be hitched with rolling or sliding means, carried or self-propelled.

L'organe de coupe 1 est une barre de coupe droite transversale et perpendiculaire au sens d'avancement de la machine.
Elle est actionnée de toute manière connue, soit par exemple au moyen d'une transmission reliée à la prise de force d'un véhicule tracteur, soit par exemple au moyen d'un moteur hydraulique.The cutting member 1 is a transverse straight cutter bar and perpendicular to the direction of advance of the machine.
It is actuated in any known manner, either for example by means of a transmission connected to the power take-off of a tractor vehicle, or for example by means of a hydraulic motor.

Il va de soi qu'à la barre de coupe du type faucheuse peut etre substitué tout moyen équivalent adapté ou adaptable tels que des disques faucheurs ou autres.It goes without saying that any mower type cutter bar can be substituted with any equivalent or suitable means such as mowing discs or the like.

L'organe de destruction est constitué par une chambre 2A qui reçoit les fanes et que est dotée d'un fond 4 totalement ou par­tiellement ajouré en forme de grille, de parois latérales 5 et d'une paroi transversale arrière 6 partiellement ou totalement ajourée en forme de grille.
L'organe 3 de translation et transport de fanes coupées de la zone 1A vers la zone 2A est constitué par au moins un volet mobi­le 7 suivant un mouvement cyclique de la zone 1A à la zone 2A.The destruction member is constituted by a chamber 2A which receives the haulms and which is provided with a bottom 4 totally or partially perforated in the form of a grid, side walls 5 and a rear transverse wall 6 partially or totally perforated in grid shape.
The member 3 for translating and transporting cut haulms from zone 1A to zone 2A consists of at least one movable flap 7 following a cyclic movement from zone 1A to zone 2A.

Selon l'invention, le volet 7 est constitué de deux parois trans­versales au sens d'avancement de la machine, parallèles à la bar­re de coupe et montées de préférence dans un meme plan de part et d'autre d'un axe 8 rotatif par tous moyens connus telle que par exemple la manivelle représentée à la figure 2.According to the invention, the flap 7 consists of two transverse walls in the direction of advance of the machine, parallel to the cutter bar and preferably mounted in the same plane on either side of a rotary axis 8 by all known means such as for example the crank shown in Figure 2.

Lors de l'avancement de la machine, les fanes du rang d'asperges sont sectionnées par la barre de coupe ; pendant ce sectionne­ment, une des parois 7A les rabat vers la barre de coupe puis les pousse vers la zone 2A, l'autre paroi 7B adoptant une position diamètralement opposée à la précédente en sorte que lorsque la paroi 7A est à la verticale de la barre de coupe, la paroi 7B soit au-dessus à la meme position en obturation entre les zones 1A et 2A.As the machine advances, the asparagus row tops are cut by the cutter bar; during this sectioning, one of the walls 7A flaps them towards the cutter bar and then pushes them towards the zone 2A, the other wall 7B adopting a position diametrically opposite to the previous one so that when the wall 7A is vertical to the bar section, the wall 7B is above at the same closed position between the zones 1A and 2A.

Selon cette forme simplifiée de réalisation de l'invention, une paroi articulée 9 suivant un axe d'articulation supérieur et parallèle à l'axe 8, est fixée transversalement au sens d'avance­ment de la machine sur un montant supérieur de la chambre 2A dont l'ouverture correspond à la position de l'organe 3.
Cette paroi 9 est poussée vers l'extérieur pour le passage du volet 7A et reprend ensuite sa position jusqu'au passage du volet 7B.According to this simplified embodiment of the invention, an articulated wall 9 along an upper articulation axis and parallel to the axis 8, is fixed transversely to the direction of advance of the machine on an upper upright of the chamber 2A, the opening corresponds to the position of the member 3.
This wall 9 is pushed outward for the passage of the flap 7A and then resumes its position until the passage of the flap 7B.

La chambre 2A est de préférence dotée d'une paroi 10 formant toit et elle peut etre dotée d'un bruleur non représenté, alimenté par exemple par une bombone de gaz pour mettre le feu aux premiè­res fanes coupées, les autres prenant le feu par contact avec les premières et les cendres tombent au sol.Chamber 2A is preferably provided with a wall 10 forming a roof and it can be provided with a burner (not shown), supplied for example by a gas bomb to ignite the first cut tops, the others taking fire by contact. with the first and the ashes fall to the ground.

La figure 2 est une vue de face de la machine selon la figure 1 avec représentation du chassis support 11 doté d'un arrimage à l'attelage en trois points d'un véhicule tracteur et d'une roue 12.FIG. 2 is a front view of the machine according to FIG. 1 with a representation of the support frame 11 provided with lashing to the three-point hitch of a towing vehicle and a wheel 12.

Une roue peut également etre montée de manière à etre réglab­le en position ou escamotable latéralement à la chambre 2A de l'autre coté de la machine par rapport à la roue 12, soit pour régler la hauteur de travail par rapport au sol, soit pour faci­liter le déplacement sur route et accroitre la stabilité.A wheel can also be mounted so as to be adjustable in position or retractable laterally to the chamber 2A on the other side of the machine relative to the wheel 12, either to adjust the working height relative to the ground, or to facilitate traveling on the road and increasing stability.

Aux figures 3 et 4 est représentée une autre forme de réalisation de l'invention comprenant comme la précédente un organe de coupe 1, avec zone de coupe 1A, un organe 2 ou chambre de destruction 2A, un dispositif 3 de translation des fanes et d'obturation, l'ensemble étant porté par un chassis avec arrimage à l'attelage en trois points d'un véhicule tracteur.In Figures 3 and 4 is shown another embodiment of the invention comprising, like the previous one, a cutting member 1, with cutting area 1A, a member 2 or destruction chamber 2A, a device 3 for translating the haulms and d '' shutter, the assembly being carried by a chassis with lashing to the three-point hitch of a towing vehicle.

Selon cette forme de réalisation, le dispositif 3 est constitué par un tambour 13 monté sur le chassis au-dessus de la barre de coupe actionnée par un moteur hydraulique M1, constitué de deux joues 14 parallèles réunies par une paroi en arc-de-cercle ména­geant une entrée 15 en avant de la barre de coupe et une sortie 16 à l'arrière de celle-ci.According to this embodiment, the device 3 is constituted by a drum 13 mounted on the chassis above the cutter bar actuated by a hydraulic motor M1, consisting of two parallel cheeks 14 joined by a wall in an arc providing an inlet 15 in front of the cutter bar and an outlet 16 at the rear thereof.

Dans le tambour 15 est monté un axe central 17 entre les joues 14 entrainé en rotation par un moteur hydraulique M2.
Sur l'axe 17 sont fixées quatre parois 18 transversales au tam­bour et au sens d'avancement de la machine formant pale.
Les quatre parois sont disposées à 90° les unes des autres.In the drum 15 is mounted a central axis 17 between the cheeks 14 rotated by a hydraulic motor M2.
On the axis 17 are fixed four walls 18 transverse to the drum and to the direction of advance of the blade forming machine.
The four walls are arranged at 90 ° from each other.

Selon une forme non représentée de réalisation de l'invention, elles sont non planes, comme représenté mais incurvées.According to an unrepresented embodiment of the invention, they are not planar, as shown but curved.

Lors de la rotation de l'axe 17, au moins une paroi 18 est néces­sairement en position d'obturation de l'ouverture arrière du tam­bour tandis qu'une autre paroi 18 rabat les fanes vers la barre de coupe puis les pousse vers la chambre 2A.
La chambre 2A est dotée au niveau de la sortie 16 du tambour d'u­ne rampe 18 inclinée en arc-de-cercle et d'un fond 10 constitué par une grille vibrante sur ses supports 21 par tous moyens con­nus pour l'évacuation des cendres.When the axis 17 rotates, at least one wall 18 is necessarily in the closed position of the rear opening of the drum while another wall 18 folds the haulms towards the cutter bar and then pushes them towards the chamber 2A.
Chamber 2A is provided at the outlet 16 of the drum with a ramp 18 inclined in a semicircle and a bottom 10 constituted by a vibrating grid on its supports 21 by any known means for the removal of the ashes .

En partie supérieure de la chambre 2A est monté un déflecteur 22 transversal qui reçoit les fanes projetées par la rotation des pales 18 sur la rampe 19 et les dévie vers la grille constituant le fond 20.
La chambre 2A est dotée d'un toit 10 et son fond transversal est doté d'une ouverture 23 d'évacuation des fumées.In the upper part of the chamber 2A is mounted a transverse deflector 22 which receives the haulms projected by the rotation of the blades 18 on the ramp 19 and deflects them towards the grid constituting the bottom 20.
The chamber 2A has a roof 10 and its transverse bottom has an opening 23 for discharging the fumes.

En amont de cette ouverture est montée dans la chambre 2A une cheminée interne 24 avec chicane 25 pour éviter une propagation des flammes à l'extérieur.Upstream of this opening is mounted in the chamber 2A an internal chimney 24 with baffle 25 to prevent the spread of flames outside.

Le chassis de la machine est porté par une roue 26 avec vérin 27 pour escamoter la dite roue ou régler la hauteur de travail de la machine.
Selon cette forme de réalisation de l'invention, les joues 14 contribuent avec les pales 17 à assurer une étancheité constan­te entre la zone de coupe 1A comprise entre elles et la zone de destruction par brulage.The chassis of the machine is carried by a wheel 26 with cylinder 27 to retract said wheel or adjust the working height of the machine.
According to this embodiment of the invention, the cheeks 14 contribute with the blades 17 to ensuring a constant seal between the cutting zone 1A lying between them and the zone of destruction by burning.

Il va de soi que la machine selon l'invention peut etre simpli­fiée par suppression du dispositif transporteur 3, les fanes cou­ pées étant poussées vers la chambre 2 par avancement de la machi­ne.It goes without saying that the machine according to the invention can be simplified by eliminating the conveyor device 3, the haulm necks swords being pushed towards chamber 2 by advancing the machine.

La machine selon l'invention peut recevoir des aménagements et des variantes dans le domaine des équivalents techniques sans pour autant sortir du cadre du présent brevet.The machine according to the invention can receive arrangements and variants in the field of technical equivalents without departing from the scope of this patent.
